Happy Hot Tubs - the best for your hot tub

Spa TA Plus is used to increase your hot tub or pool water alkalinity.


Total Alkalinity must be maintained at between 80-140mg/I (ppm). 

Test this using test strips, if your TA is below 80mg/l (ppm) use TA plus to bring the level up to the recommended levels.


Having a more balanced Alkalinity ensures that your PH is more easily balanced, ensuring your spa water is less irritating and a more enjoyable experience. High TA can also cause green water and will destroy your jets, keep at 80-120 for Happy Hot Tubbing!
